The Twelve Tasks of Asterix (Les Douze travaux d'Astérix) is an animated feature film based on the Asterix comic book series. René Goscinny and Albert Uderzo, the creators of the series, wrote the story and directed the film themselves; with co-direction by Pierre Watrin and the screenplay co-written by Pierre Tchernia, a friend of Goscinny and Uderzo. The movie directed and produced at Goscinny and Uderzo's own Idefix Studios. It's the first and so far the sole Asterix animated movie based on an original screenplay rather than a published comic book, even though it was later adapted into a comic book as well as an illustrated text story book and a series of twelve books for young readers
